The CA business is all about selling trust. After all a CA is supposed to be a trusted third party. Let's hope all the remaining ones get the right message: it's not about not getting caught being hacked. On the contrary: it's about doing the right thing once you have been hacked. Let's hope it leads to more transparency and public scrutiny of the CAs we trust explicitly or implicitly though the choice of some of our vendors.
